as may be reached in the time available. If possible, sufficient time 

 should be spent in each locality to enable an examination to be made 

 of each kind of locust habitat represented in its vicinity. This will 

 give a good general idea of the locust fauna of that locality and may 

 usually be done in from one to three days of field-work, according to 

 the weather, the character of the locality, the number of habitats 

 represented, their accessibility, etc. This method, however, is often 

 impracticable when it is necessary to cover a large extent of country 

 in a limited time. 



OUTLINE OF TRIP. 



At the beginning of the season of 1905 it was planned to continue 

 investigations by making a general reconnaissance similar to that of 

 1903, during the summer vacation, in the next group of States west of 

 those examined in that year, viz, Tennessee, Alabama, Mississippi, 

 Louisiana, and Arkansas. Accordingly, passage was taken July 5 

 for Chattanooga, via Washington and Cincinnati, in order to secure 

 at first hand, albeit from a car window, some knowledge of the physical 

 conditions with reference to locust habitats which are found in southern 

 Ohio, eastern Kentucky, and Tennessee, a region not previously 

 examined in person. 



Collecting was begun on Sand Mountain plateau in the vicinity 

 of Trenton, Georgia, a point visited late in the season of 1903, in order 

 to secure data, if possible, on those species appearing in the adult stage 

 only early in the season (see fig. i). Other stops were made at 

 Valley Head, Alabama, to visit Lookout Mountain; Anniston, the 

 readiest point of approach to Cheaha Mountain, the highest summit 

 in Alabama, and Tuscaloosa. During this portion of the trip it was 

 learned that the season was very backward, both vegetation and locusts 

 being late in development, probably owing to the excessive amount 

 of cool and rainy weather of the spring months. In consequence of 

 this fact I hastened southward to Gulfport, Mississippi, on the Gulf 

 coast, stopping at Meridian and Hattiesburg en route. After three 

 days spent there and at near-by points the presence of yellow fever in 

 New Orleans was announced, and in the hope of being able to do the 

 work planned for that vicinity and get away before freedom of travel 

 was interfered with, should that difficulty arise, I went immediately 

 to New Orleans and spent one day in the suburbs and another in a 

 trip down-rivet and back to the marsh region at Buras, the present 

 terminus of the railroad. Learning that if I remained in the city 

 longer there was every likelihood of enforced and probably prolonged 

 delay, I went west to Franklin, with the intention of collecting there
